The Lord God Almighty is very reasonable. If he asks us to accomplish a task, it usually is something that we can accomplish. He never gives us a task that would be impossible for us to accomplish, nor does he ever give us a task that would not serve the purposes of his kingdom.
If you have a commission from the Lord God Almighty, know that he is with you, and that he will never leave you, nor forsake you. Do the task he has called you to do, and your reward will be great. The Lord God Almighty is a God of reason.
